Manufacturers sometimes see variation in dispensing performance when there is even a slight change in the tolerance of a jet valve’s internal geometry. Therefore, one jet valve may produce a slightly different dispensing outcome than another with the same dispense settings. This is also why dispensing outcomes can sometimes change after a fluid body is removed, cleaned for maintenance, and then returned to valve.

The PICO XP jetting system’s proprietary self-regulating calibration technology controls for variations in fluid body tolerance to maintain the same micro-dispensing repeatability from valve-to-valve and after maintenance.
